摘要
改善和优化土地利用方式是综合治理黄土高原水土流失的关键,以黄土高原小流域的恢复生态、提高土地生产力、实现经济可持续发展为目的,以渭北西部丘陵沟壑区的典型流域为例,对陕西千阳县冉家沟小流域进行生态规划与设计。主要包括小流域土地利用现状分析、土地生态类型的评价、土地利用系统的结构优化及土地利用的生态设计与规划等。
To improve and optimize land use pattern and structure is one of the most effective ways to control soil erosion in the hill-gully Loess region. We had taken the small watershed of Ranjiagou with typical characteristics of hilly-gully region in Weibei Loess Plateau, focusing on restoring ecological system in this small watershed, to improve land productivity and achieve sustainable development of economy. The main procedures include land use system analysis, eco-landuse type evaluation, optimization of land use system, and eco-designing of the optimum land use system.
